Flickering on my metal bars 3d model

Hello everyone! I’m an amateur game developer currently working on a project with some high-school friends. Our project is in early prototyping stages.

I just finished up making a metal bars 3d model. When imported into unity, the 3d model has strange flickering behavior. I made sure it wasn’t due to overlap with another object, and that it wasn’t duplicated - so the flickering isn’t because of z-fighting.

Would appreciate anyone who could help point me in the right direction. I could live with this behavior, but it’s rather distracting
